Research Highlights

Our new spatial output indexes show that 16 to 21 percent of the increase in U.S. corn output over the 128 years beginning in 1879 was attributable to spatial movement in production.

Model-estimated yield variability of rainfed maize with high input for 1981-2010 (30-year period). Values are for 5 arc-minute grid cells.

We clarify the terminology surrounding yield gaps, show that closing yield gaps is not necessarily economic, and conclude that food security will be better served by policies that directly enhance the productive capacity of agriculture to supply affordable food efficiently and sustainably.

Study evaluates the potential impacts of 'Drought Tolerant Maize for Africa' project run by CIMMYT and IITA in 13 sub-Saharan African countries.

Cover Atlas of African Ag

Years of weathering have leached nutrients away from many soils in the cropped areas of Africa south of the Sahara (SSA).

This tool helps users to identify specific sites within the SAGCOT (Southern Agricultural Growth Corridor of Tanzania) area where new irrigation investments should target at 10 km spatial resolution.

HarvestChoice Mappr mentioned among 9 datasets to improve your ICTforAg programs.

Soil organic carbon content (fine earth fraction) at 15-30cm depth.

The purpose of this series of country briefs is to provide a comprehensive and standardized view of agricultural characteristics, integrat- ed with socio-economic variables across countries.

Through open access global and household datasets, pseudo-panels, spatial data analytics and communities of practice, data are increasingly available to support investment portfolios designed to enhance the resilience of vulnerable populations in the Horn of Africa.
